Study on the Treatment and Intermediates Formation of Azo Dye Wastewater by the Combined Nano Catalytic Electrode with Electrocatalytic Technology
Using electrocatalytic technique to treat wastewater has been paid attention for a decade. The hydroxylradicals produced by the interaction between the catalytic electrode and water molecule in the aquatic systemare effectively to degrade organic pollutants into harmless water and carbon dioxide, which achieved aim ofclarify of water. The electrocatalytic technique is particularly advantageous as high efficiency, equipmentsimple, easy control, which possess high potential and attention. In this study, the degradation of dyewastewater by integrates the different catalytic electrodes with electrocatalytic technique was evaluated.The tasks in this study include (1) degradation of azo dye wastewater by electrocatalytic technique. Toinvestigate the removal efficiency of total organic carbon and color of wastewater under difference operatingcondition, which to find out the appropriate operation parameters; (2) degradation of intermediate product byelectrocatalytic technique, which to understand the effect of intermediate product during the treat process.The result conducted the reference of real factory degradation; (3) combination of nano catalytic electrodeand electrocatalytic technique to degradation of wastewater from the real factory. Discussion of the treatefficiency by various condition. Meanwhile, the stability and the economic benefits of this technique will beevaluated by current efficiency and energy consumption. The ones that used are practical in order to giveconsideration to the theoretical foundation and real factory.
